Question

我正在使用io.github.divinespear：jpa-schema-maven-plugin：0.1.12插件生成我的sql脚本。过去效果不错，但最近已停止工作。特定的错误消息是：

[ERROR] Exception Description: An exception was thrown while searching for persistence archives with ClassLoader: java.net.URLClassLoader@28a6301f
[ERROR] Internal Exception: javax.persistence.PersistenceException: Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.EntityManagerSetupException
[ERROR] Exception Description: Predeployment of PersistenceUnit [userService] failed.
[ERROR] Internal Exception: Exception [EclipseLink-7161] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.ValidationException
[ERROR] Exception Description: Entity class [class my.firm.integration.sp.usermanager.entity.PermissionEntity] has no primary key specified. It should define either an @Id, @EmbeddedId or an @IdClass. If you have defined PK using any of these annotations the
n make sure that you do not have mixed access-type (both fields and properties annotated) in your entity class hierarchy.

我的某些实体使用@MappedSuperclass，但是此类未定义主键。我不会混合访问类型。

因为我已经在这个项目上工作了一段时间，但是很少添加新实体或更改现有实体，所以我无法确定插件停止工作的时间。回到以前的提交并没有改变结果，在这一点上，我不得不假设它是另外一回事。

以下是示例实体，相关代码和配置：

PermissionEntity.java：

package my.firm.integration.sp.usermanager.entity;

import my.firm.integration.sp.userauthentication.dto.PermissionDTO;
import lombok.Data;

import javax.persistence.*;
import java.util.Map;
import java.util.stream.Collectors;

@Entity
@Data
@Table(name = "PERMISSIONS")
public class PermissionEntity extends VersionedEntity {
    @Id
    @GeneratedValue
    @Column(name = "ID")
    private String id;

    @Column(name = "PERMISSION_ID")
    private String permissionId;

    @ManyToMany(cascade = CascadeType.ALL)
    private Map<String, PermissionAttributeValueEntity> permissions;

    public PermissionDTO toDTO() {
        PermissionDTO dto = new PermissionDTO();
        dto.setId(id);
        dto.setPermissionDefinitionId(permissionId);
        dto.setFields(permissions
                .entrySet()
                .stream()
                .collect(Collectors.toMap(
                        Map.Entry::getKey, entry -> entry.getValue().toDTO())));
        return dto;
    }
}

persistence.xml：

        </properties>
    </persistence-unit>
</persistence>

eclipselink-orm.xml：

        <multitenant type="SINGLE_TABLE">
        </multitenant>
    </entity>
</entity-mappings>

我pom.xml中配置的插件：

<plugin>
    <groupId>io.github.divinespear</groupId>
    <artifactId>jpa-schema-maven-plugin</artifactId>
    <version>0.1.12</version>
    <configuration>
        <scriptAction>create</scriptAction>
        <dialect>dummy</dialect>
        <databaseProductName>${database.productName}</databaseProductName>
        <persistenceUnitName>userService</persistenceUnitName>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.4.0</version>
        </dependency>
        <dependency>
            <groupId>com.microsoft.sqlserver</groupId>
            <artifactId>mssql-jdbc</artifactId>
            <version>6.1.0.jre8</version>
        </dependency>
    </dependencies>
</plugin>

当我使用以下maven命令：mvn -Ddatabase.productName="Microsoft SQL Server" jpa-schema:generate时，我希望将架构放置在target/generated-schema文件夹中，但是会发生上述错误。

Eclipselink声称使用jpa-schema-maven-plugin生成迁移方案时，我的实体没有定义主键
